  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Client client.

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the GatewayControl Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

Yield Parameters:

#generate_credentials(request, options = nil) ⇒ ::Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsResponse #generate_credentials(name: nil, force_use_agent: nil, version: nil, kubernetes_namespace: nil, operating_system: nil) ⇒ ::Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsResponse

GenerateCredentials provides connection information that allows a user to access the specified membership using Connect Gateway.

Examples:

Basic example

require "google/cloud/gke_connect/gateway/v1beta1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::GkeConnect::Gateway::V1beta1::GatewayControl::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsRequest.new

# Call the generate_credentials method.
result = client.generate_credentials request

# The returned object is of type Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsResponse.
p result

Overloads:

  • #generate_credentials(request, options = nil) ⇒ ::Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsResponse

    Pass arguments to generate_credentials via a request object, either of type Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #generate_credentials(name: nil, force_use_agent: nil, version: nil, kubernetes_namespace: nil, operating_system: nil) ⇒ ::Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsResponse

    Pass arguments to generate_credentials via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • name (::String) (defaults to: nil) —

      Required. The Fleet membership resource.

    • force_use_agent (::Boolean) (defaults to: nil) —

      Optional. Whether to force the use of Connect Agent-based transport.

      This will return a configuration that uses Connect Agent as the underlying transport mechanism for cluster types that would otherwise have used a different transport. Requires that Connect Agent be installed on the cluster. Setting this field to false is equivalent to not setting it.

    • version (::String) (defaults to: nil) —

      Optional. The Connect Gateway version to be used in the resulting configuration.

      Leave this field blank to let the server choose the version (recommended).

    • kubernetes_namespace (::String) (defaults to: nil) —

      Optional. The namespace to use in the kubeconfig context.

      If this field is specified, the server will set the namespace field in kubeconfig context. If not specified, the namespace field is omitted.

    • operating_system (::Google::Cloud::GkeConnect::Gateway::V1beta1::GenerateCredentialsRequest::OperatingSystem) (defaults to: nil) —

      Optional. The operating system where the kubeconfig will be used.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
